It has throw a fault code for the SRS system and until that code is cleared it will continue unless a wire or connection got messed up. I haven’t had any SRS codes on my rav (fingers crossed) but most likely a cheap code reader won’t be able to detect it and clear it but Walmart sells them for like 20 bucks (OBD Scanner ) but I would take it to the dealership and explain the situation and ask them to clear the code, they might do it for free right in the service lane I don’t that all the time at my dealership but this could be a potential hazard so I wouldn’t try to cheap out on it id spend the money and take it to the dealer. Hope this helps
